--check-config option now prints names of last 5 installed

Until now, './project --check-config' would only print the names of the
software that were being built. Besides that, it is also useful to know
which packages have most recently finished.

With this commit, we now print the last 5 built software packages with
'--check-config' also, and the output has also been placed in a row of '='s
to help separate it in each round. Also some more sanity checks have been
added so it doesn't print error messages.
